Letters Patent No. 97,211, dated November 23, 1869.

, IIVIPROVEMENT IN LOCOMOTIVE HEAD-LIGHTS.

The Schedule referred to 'in these Letters Patent and.- making part of the same.

I, LEWIS ,MICHAELS, of Oincinnathin the county of Hamilton, and State of Ohio, have invented a cer-. tain Improvement; in Hydrocarbon Lamps for -Locomotive Head-Lights, of which the following is a specification.

My invention has especial reference to the class of hydrocarbon lamps employed in locomotive headlights, and is designed to relieve such lamps of their present serious liability to melt down and give out, sometimes, on very critical occasions, involving the safety of the train itself.

Figure 1 is an axial section of a lamp embodying my invention. v

Figure 2 is a perspective view of the combined collar and oil-funnel, with the rack-sheath shown detached.

Figure 3 is a horizontal section at X-X.

The most distinguishing feature of inyimprov ment is a single casting, A, which takes the place of some six separately-soldered pieces in the customary head-light lamp, which pieces are liable to become detached, either by constant mechanical agitation, or by the action-of heat, when the lamp takes fire.

The piece or casting A is composed essentially of the following parts, to wit:

An annular pit, a, which constitutes the bottom of the wick-chamber; two female screw-threads, a a, for the respective attachment of the inner and outer .wick-tubes B and O; a screw-threaded orifice in its bottom, for the rack-sheath D; and projecting ohliquely-from one side, a duct or funnel, a, which conveys oil from a, customary reservoir, E.

Thepiece A also hasscrew-holes, for the screws E, which take the place of solder in the attachment of the waste-spout G and receptacle H.

a" is a slot -iu the casting A, to receive and confine the rack. Y
